The goal of this study was to improve the poor state of calcareous sand loamy soil, increase its efficiency, and convert the negative impact of certain by-products, such as sugar beet waste (low economic value), on pollution into a positive impact on agricultural soil qualities. The effect and residual effect of different organic amendments (sugar beet waste (S.B.W.), compost (Comp), sugar beet waste 50 percent combined with compost 50 percent application under two different tillage practices of tillage surface (P1) and deep tillage (P2) on some soil hydro-physical and chemical properties, as well as canola and sunflower seeds yields tonfed -1 , were investigated. In the first and second years for surface tillage P1, employing (S.B.W) in combination with compost treatment yielded the greatest values of O.C percent. 83 percent and O.C.F 17.7 percent, respectively. The addition of diverse organic amendments had a substantial influence on each of the hydro-physical and chemical parameters, such as USC and Db, with the lowest values for Db being in the second winter season, highlighted by S.B.W. mixed with compost treatment. Applying the same treatment under deep tillage technique (P2) 2.79, 2.8 USC for two summer seasons, respectively, yielded the lowest USC value. The application of mixed sugar beet with compost treatment resulted in the greatest mean values for Kh (cmh -1 ), I.R (mmh -1 ) and porosity percent, which were 3.92 P2 Kh (cmh -1 ), 6.94 P2 I.R (mmh -1 ) and 50 P2 E percent for both winter seasons. Data indicated that when various organic amendments were applied to big aggregate size fractions >2mm (by percentage), the aggregate sizes dispersion tended to increase. In comparison to the control treatment, 4.05 percent S.B.W, 13.76 percent Comp, and 15.8 percent combination S.B.W with compost treatments were found. For both surface and deep tillage, the greatest values for aggregate state and degree owing to treatment (Comp and S.B.W) were about 72.88 percent aggre. state and 76.6 percent aggre. Degrees also account for 42 percent of aggre. state and 47.95 percent of aggre. degrees, respectively. The greatest mean A.S.I values were achieved using the (Comp and S.B.W) treatments with P1 (0.82) and P2 (0.7), respectively. Which were thought to be excellent A.S.I. Conversely, the largest seed yields of canola or sunflower plants were achieved with the application of S.B.W mixed with Comp. by both surface and deep tillage, yielding 1.19 (P1), 0.981 (P2) ton fed -1 of canola plant and 1.56, and 1.51ton fed -1 of sunflower plant, respectively.

Saline soil is one of the major abiotic stresses that minify plant growth and crop productivity in arid and semiarid regions. A pot experiment was conducted during the summer season of 2019 to evaluate the effect of zeolite and urea fertilizer on growth and yield of maize grown under saline conditions. The experiment design was Factorial RCBD with four replicates, the first factor was zeolite level {0 (control), 2, 4 and 6 %} and the second factor was urea fertilizer level {0 (control), 30, 60 and 90 kg N/fed}. Results showed a significant increase in the vegetative growth characteristics of maize i.e. plant height, fresh and dry weight, total chlorophyll (SPAD), and leaf area under zeolite application treatments as compared with control (0% zeolite). Among the studied zeolite rates, 6% zeolite treatment resulted the highest vegetative growth parameters. Moreover, the application of urea fertilizer at 90 kg N/fed recorded the highest values of vegetative growth parameters, as compared with untreated treatment (control) which gave the lowest values of these traits. Zeolite application also enhanced plant NPK content and soil available NPK as compared with the untreated soil. The highest plant NPK content and soil available NPK were recorded under 6% zeolite rate. Similarly, application of 90 kg N/fed of urea fertilizer produced the highest plant NPK content and soil available NPK as compared with control. These results revealed that zeolite amendment mitigated salt stress, improved plant growth, and enhanced absorbing nutrients by plant and retaining nutrients in soil. The results concluded that zeolite amendment can be an efficient tool to increase crop productivity and food production, reduce nutrient losses and environmental pollution, and to expand the agricultural utilization of the low-quality soil in arid and semi-arid regions.
盐碱地是干旱和半干旱地区影响植物生长和作物生产力的主要非生物胁迫之一。2019年夏季，通过盆栽试验，研究了沸石和尿素肥对盐碱条件下玉米生长和产量的影响。试验设计为析因RCBD，共设4个重复，第一因子为沸石水平{0(对照)、2、4和6%}，第二因子为尿素水平{0(对照)、30、60和90 kg N/料}。结果表明，与对照(0%沸石)相比，施用沸石处理显著提高了玉米的营养生长特征，即株高、鲜重和干重、总叶绿素(SPAD)和叶面积。在所研究的沸石浓度中，6%沸石处理的营养生长参数最高。氮素/投喂量为90 kg的尿素处理的营养生长指标最高，而未处理(对照)的营养生长指标最低。与未处理的土壤相比，施用沸石也提高了植株氮磷钾含量和土壤有效氮磷钾含量。在6%沸石率下，植株氮磷钾含量和土壤有效氮磷钾含量最高。同样，与对照相比，施用90 kg N/ d尿素肥的植株氮磷钾含量和土壤有效氮磷钾含量最高。结果表明，沸石改性可以缓解盐胁迫，促进植物生长，增强植物对养分的吸收和土壤中养分的保留。结果表明，沸石改性是提高干旱半干旱区低质量土壤的作物生产力和粮食产量，减少养分损失和环境污染，扩大农业利用的有效工具。

Two field experiments were conducted during two winter successive seasons 2019/2020 and 2020/2021 at the National Research Station, Area, Egypt. The purpose of the study was to investigate the link between vegetative development, yield, yield components, and numerous metabolic variables components of the "Giza 716" Egyptian faba bean cultivar (Vicia faba L.) to foliar application of three growth regulators; paclobutrazol (PBZ; 30, 60 and 90 ppm), mepiquat chloride (MC; 500, 1000 and 1500 ppm) and baritone (AGR; 400, 600 and 800 ppm). The foliar application of PBZ, MC, and AGR had positive effects on all growth and yield parameters. On the other hand, the three growth regulators reduced plant height, fresh and dry weights of branches and leaves/plant, fourth leaf area and leaf area index, specific leaf weight, crop growth rate, net assimilation rate, relative growth rate, and yield (number of pods per plant, number of seeds per pod, pod weight/plant, seed and straw yield/plant, seed and straw yield/feddan, seed index), and harvest index), when used in high concentrations. By boosting total carbs, crude protein, total free amino acids, nitrogen, phosphate, and potassium, PBZ, MC, and AGR considerably boosted total photosynthetic pigments content in leaves and improved seed quality and nutritional value. Generally, foliar application of PBZ, MC, and AGR When used at low quantities, it had a favorable impact on growth parameters, photosynthetic pigments, seed yield and yield components, as well as several biochemical components of the faba bean seeds yield. net assimilation rate (NAR), and relative growth rate (RGR), as compared with untreated control plants, highly significant. Data also show the most effectiveness treatments were AGR at 400 and 600 ppm followed by PBZ at 30 ppm for all growth parameters. Foliar application of PBZ up to 60 ppm, significantly increased the area of fourth leaf (4 th LA), leaf area index (LAI), specific leaf weight (SLW), crop growth rate (CGR), net assimilation rate (NAR), and relative growth rate (RGR) compared with relevant untreated control units. compared control plants.

Surface geophysical survey was performed along Qift EL-Quseir Road between the Red Sea coast at the east and Qift town at the River Nile westward, Central Eastern Desert, Egypt, to delineate its groundwater situation. The groundwater in this hyper-arid area has a precious value for the different development objectives. The study area is characterized by presence of several aquifers (fracture basement, Nakheil formation, Nubian sandstone and Quaternary aquifers). These aquifers represent the main source of groundwater that used in tourist activities, mining and agriculture projects. The integration between surface geophysical techniques (land magnetic profiles, vertical electrical soundings (VES's) and electric resistance tomography), cover all gaps in study area. These surveys determine the horizontal and vertical extensions of the lithological succession, estimate the aquifers dimensions, the depth to water, the water level, estimate the characteristics of the water bearing formations, detect the basement relief, geological structures that affect the groundwater occurrences, locate the best sites for drilling productive water wells and finally Assess the groundwater potentialities in the study area. From this geophysical study, it can be mentioned that the promising sites for digging new productive water wells are, the delta of Fawakheir–Mathula basin, the Nubian sandstone plateau area (between km 15 to km 65 East the Nile), localities of El Sid and the downstream portion of W.Um Slimat, location of the delta of Abu Zeran-Ambagi basin (between km 2 to km9 from the Red Sea coast) and the downstream of W.El Nakheil sub-basin. Some exploratory drilling wells can be recommended in downstream portions of W.Kareem, El Beida area, W.Hamad and El Sheikh Abd Al'al region.

Nowadays, the main task of food producers is to make new tasty gluten-free products with an elevated nutritive value to enrich the menu of celiac patients. One of such products could be sweets, such as cake and cookies. Therefore, unpuffing popcorn flour (raw popcorn flour RPF), puffing popcorn corn flour (PPF) and a mixture (1:1) from them, in addition to corn flour as a control sample, were used to prepare gluten-free cake and cookies formulas. The lowest amylose content (19.81 %) of corn flour followed by raw popcorn flour (22.97%) and popped popcorn (24.95 %). Gluten free cake prepared from popped popcorn (PPF) recorded the highest volume (395 cm), weight (201.51 g), height (6.63 cm) and specific volume (2.22 cm/g), while gluten free cake prepared from PPF had the lowest values which were 367.33 cm3, 185.42 g, 4.75 cm and 1.94 cm/g, respectively. The highest Fracturability was recorded in the control (65.25 N) while the lowest value (53.48 N ) was recorded in PPF cookies. Thus, the higher cake expansion and in turn higher specific volume would be an expected product of popping process. The lowest rate of Hardness values was noticed after storage period (5 days) in PPF cake samples. Rate of chewiness, gumminess and resilience also were the lowest values in PPF cake samples. Generally, PPF based cookies (cake prepared from popped popcorn) were more acceptable as it had the highest overall acceptability sensory attributes in both prepared cake and cookies.

One of such products could be sweets, such as cake and cookies. Therefore, unpuffing popcorn flour (raw popcorn flour RPF), puffing popcorn corn flour (PPF) and a mixture (1:1) from them, in addition to corn flour as a control sample, were used to prepare gluten-free cake and cookies formulas. The lowest amylose content (19.81 %) of corn flour followed by raw popcorn flour (22.97%) and popped popcorn (24.95 %). Gluten free cake prepared from popped popcorn (PPF) recorded the highest volume (395 cm), weight (201.51 g), height (6.63 cm) and specific volume (2.22 cm/g), while gluten free cake prepared from PPF had the lowest values which were 367.33 cm3, 185.42 g, 4.75 cm and 1.94 cm/g, respectively. The highest Fracturability was recorded in the control (65.25 N) while the lowest value (53.48 N ) was recorded in PPF cookies. Thus, the higher cake expansion and in turn higher specific volume would be an expected product of popping process. The lowest rate of Hardness values was noticed after storage period (5 days) in PPF cake samples. Rate of chewiness, gumminess and resilience also were the lowest values in PPF cake samples. Generally, PPF based cookies (cake prepared from popped popcorn) were more acceptable as it had the highest overall acceptability sensory attributes in both prepared cake and cookies.","PeriodicalId":273673,"journal":{"name":"Middle East Journal of Applied Sciences","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121292168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
